Family members of those killed in the Miami-area condominium collapse are visiting the wreckage Sunday afternoon for a private event. 

"This is a private and deeply emotional moment for them, and we appreciate everyone's respect for the families," the office of Miami-Dade County Mayor Daniella Levine Cava told Fox News.

    • The Champlain Towers in Surfside, Florida, partially collapsed early Thursday morning

The announcement came as the death toll from the Champlain Towers South Condo collapse rose to at least nine people on Sunday, with four of those having been identified, while more than 150 still remain unaccounted for. 

Miami-Dade Mayor Daniella Levine Cava announced the heightened toll at an evening news briefing, saying the identification of three bodies had dropped the number of unaccounted for down to 156. She said crews also discovered other unspecified human remains.

The Miami-Dade Police Department said later Saturday that four of the five deceased people had been identified, along with the apartments where they were at the moment of the collapse. One of them was the mother of a boy who was rescued the morning the building toppled. 

They were identified as Stacie Dawn Fang, 54; Antonio Lozano, 83; Gladys Lozano, 79; and Manuel LaFont, 54.

Cava said the rescuers' priority continued to be "saving as many lives as we can," heading into the third full day since the collapse early Thursday.
